FAQ
Do you develop cross-platform or native apps?
We provide both. For cost-effective launches with a shared codebase, we build using Flutter. For apps requiring deep OS-level integration, maximum execution performance, or platform-specific UI frameworks, we build natively using Swift (iOS) and Kotlin (Android).
What do I need to provide to get started?
Ideally, your Figma or UI/UX designs, a clear list of features/user stories, and access to any existing APIs or backend services. If you only have an idea or wireframe, contact us first—we can help define the MVP scope.
Will you help publish the app to the App Store and Google Play?
Yes. We guide you through setting up your Apple Developer and Google Play Console accounts, configuring the required metadata, and submitting the build through the store review process until approval.
Do I own the source code?
Yes. Once the order is completed and accepted, 100% of the intellectual property, repository rights, and source code belong entirely to you.
Can you handle backend setup and database design?
Yes. We can integrate with your existing APIs or configure a complete backend infrastructure from scratch using Firebase, Supabase, or custom REST endpoints.
What happens if there are bugs after delivery?
We provide a dedicated post-launch support window with every package to fix any bugs or technical issues related to the agreed scope of work. Continued maintenance packages are also available.
